ROUGH-ROUNDING AND CHANNELING MACHINE.

Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed. March 6, 1903. Serial No. 146,444.

To all whom it may concern:

Be it known that I, WILLIAM S. BRAINARD, a citizen of the United States,residing at West Bridgewater, in the county of Plymouth and State ofMassachusetts, have invented certain new and useful Improvements inRough- Rounding and Channeling Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same. The present invention relates to rounding andchanneling machines, and more particularly to an improvement on thewell-known Universal rounding and channeling machine of the Goodyearsystem, particularly the machine illustrated and described in LettersPatent granted to French and Meyer, No. 599,602, February 22, 1898, andespecially as modified by the invention to me illustrated in LettersPatent No. 682,315, September 10, 1901. In the said Universal r0u'ndingand channeling machine the trimmingknife trims the edge of the sole at adistance from the last determined by either the stationary guide whichmay act continuously all around the shoe or by the said stationary guidewhich guides the shoe during the operation along the shank and thefore-part guide, which guides the shoe around the fore part when Scotchor Baltimore edge shoes are being rounded and channeled upon themachine. In the said patent to me, No. 682,315, the said Universalrounding and channeling machine-is shown as provided with means forfending off the sole, so as to prevent the channeling-knife from cuttinga channel therein, which in some classes of shoes wherein the fore partis stitched aloft is desirable. In rough-rounding and channeling Scotchand Baltimore edge shoes which are to be stitched aloft it is desirableto throw the channelingknife out of operation at the same time that thefore-part guide is thrown into operation; and the object of the presentinvention is to reorganize and improve rounding and channeling machinesembodying means for throwing the channeling-knife out of and intooperation, so as to secure the throwing in of the fore-partguide and thethrowing out of the channeling-knife at the same time and by onemovement of the operator.

1 is afront elevation of so much of the Universal rounding andchanneling machine as is necessary to be illustrated in order to dis-.close my invention. Fig. 2 is a plan view of the channeling-knifecarrier and associated parts. Fig. 3 is a left side elevation of aportion of the machine provided with the present devices. Fig. 4 is amedial section of the ob anneling-knife carrier and the guard forfending oif the work from the channeling-knife, and Fig. 5 is a frontelevation of the same.

The illustrated embodiment of the present invention is described asfollows:

The rounding and channeling machine proper consists of the stationaryguide 1, the trimming-knife 2, the outside feed-plate 3, thechanneling-knife 4, the channeling-knife carrier 5, the channeling-knifeguard 6,- and the fore-part guide 7, which are constructed, operated,and arranged substantially as in said Universal rounding and channelingmachine as modified by the construction illustrated in said patent tome. The channeling-knife guard 6, for convenience hereinafter termed theknife-guard, consists of a plate pivoted at 8 to the channeling-knifecarrier 5, the said guard being cut away on the left side at its upperend in order to afford a space through which the channcling-knife4 mayproject. A spring 9 is provided which is received in a socket in thelower portion of the channeling knife carrier 5, the outer end of whichspring engages the downwardly-projected end of the guard 6 and normallytends to move the knifeguard into the position illustrated in Fig. 4. Inthis position the channeling-knife projects beyond the surface of theguard and is operative to cut a channel In the sole of a shoe. Theknife-guard is moved by means of a lever 10,-having a wedge-surface 11,which engages an inclined face 12, mounted upon the rear side of theknife-guard 6. The lever 10 is pivoted at 12* to thechanneling-knifecarrier lever 13, the arrangement being such that whenthe outer end 14 of the lever 10 is depressed the wedge-surface 11 ofthe said lever is raised, thereby forcing the inclined face 12 of theknife-guard outwardly and moving the knife-guard from the positionillustrated in Fig. 4 to the position illustrated in Fig. 3 and fendingoff the sole and preventing the operation of the channeling-knife. Alink 15 connects the lever 10 with a knee-lever 16, pivoted upon aportion of the frame of the machine, so that by this means theknifeguard may be thrown out or be permitted to be moved in by itsspring. In roundingshoes which are to be stitched aloft around the forepart and in which the sole projects a uniform distance from the last allof the way around, which distance is determined by the adjustment of thestationary guide 1, the operator, after cutting the channel and trimmingthe sole along one side of the shank of a shoe, will move the knee-lever16 so as to throw the knife-guard 6 forward, thereby fending off .thework from the channeling-knife, while the trimming-knife continues totrim the edge of the sole going around the fore part, and then willagain release the knee-lever 16, so that upon the opposite side of theshank portion the channeling-knife will again come into operation, thespring 17 secured at its lower end to the outer end 14 of the lever 10and at its opposite end to a stationary part of the machine, operatingto restore the knife-guardactuating lever 10 to its position, so thatthe spring 9 will return the knife-guard to the position illustrated inFig. 4.

In the machine of said Patent No. 599,602 the fore-part guide 7 is drawndown into position to engage thelast by means of a treadle having aconnecting-link 18, connecting it to the lever 19, carrying saidfore-part guide 7. In Scotch and Baltimore edge shoes, in which thefore-part guide 7 is thrown into operation after the completion of therounding and channeling of one side of the shank, in which shoes it isdesired to stitch aloft around the fore part, it is desirable to connectthe means for throwing the knife-guard 6 forward to fend off the solewith the means for throwing the fore-part guide 7 into operation, and tothis end the outer end 14 of the knife-guard lever 10 is connected bymeans of a link 20 with the link 18, so that upon the depression of thetreadle to throw the fore-part guide 7 into operation the knife-guard 6is simultaneously thrown forward by this connection to fend off the solefrom the action of the channelingknife at the same time. The link 20 isconnected to the link 18 in such manner that op eration of theknee-lever 16 to throw the knife-guard forward is inoperative to actuatethe fore-part guide through the means described, such connections beingas follows: The link 20 passes through a hole in the connection 21,secured to the link 18, the end of said link 20 projecting beyond saidhole, and upon such projecting portion of the link 20 a sleeve 22 issecured by means of a set-screw. Thus when the knife-guard lever isactuated by the knee lever the link 20 slides downward through the holein the connection 21 without moving said connection 21 or actuating thefore-part guide 7. By this construc'tion,therefore, when the fore-partguide is thrown into operation the knife-guard is thrown forward to fendoff the sole and to prevent the channeling-knife from cutting a channeltherein, while, if desired, the knife-guard may be thrown forwardwithout throwing the forepart guide into operation, so that the deviceis capable of being used upon differing classes of work withoutadjustment or change.

If it is desired to sever the connection between the knife-guard leverand the fore-part guide, it is simply accomplished by loosening theset-screw which secures the sleeve 22 in place upon the link 20 andsliding such sleeve down the link, so that upon a depression of thetreadle the link 18 will only actuate the fore-part guide-lever 19,thereby throwing the fore-part guide into operation without throwing theknife-guard forward to fend the sole off from the action of thechanneling-knife. In such case the machine is provided with twoindependent means for actuating the forepart guide and channel-knifeguard. It is considered, however, that the present invention isprincipally useful in operation upon shoes having Scotch or Baltimoreedges which it is desired to stitch aloft around the V fore part so thatby one movement the operator may throw the fore-part guide into and thechanneling-knife out of operation, and incidentally to provide means forthrowing the channeling knife out of or into operation independent ofthe means for throwing the fore-part guide into or out of operation.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is

1. A rough-rounding and channeling machine, having, in combination, atrimmingknife, a channeling-knife, a fore-part guide, and common meansfor throwing the fore-part guide into and the channeling-knife out ofoperation, substantially as described.

2. A rough-rounding and channeling ma chine, having, in combination, atrimmingknife, a channeling-knife, a fore-part guide,

common means for throwing the fore-part guide into, and thechanneling-knife out of, operation, and independent means for throwingthe channeling-knife out of operation, substantially as described.

3. A rough-rounding and channeling machine, having, in combination, atrimmingknife, a channeling-knife, a fore-part guide, a channeling-knifeguard, connected means for throwing the fore-part guide andchanneling-knife guard into operation, substantially as described.

4. A rough-rounding and channeling machine, having, in combination, atrimmingknife, a channeling-knife, a fore-part guide, a channeling-knifeguard, connected means for throwing the fore-part guide andchanneling-knife guard into operation, and independent means forthrowing the channelknife guard into operation, substantially asdescribed.

In testimony whereof I aflix my signature in presence of two witnesses.
